CAR-DOOR FASTENING.

SPECIFICATION forming part of Letters Patent No. 554,133, dated February4, 1896. Application filed July 11, 1895. SerialNo. 555,686. (N0 mode -lTo all whom it may concern:

Be it known that I, FRANK 'H. MEYERS, a

citizen of the United States, residing in Philadelphia, Pennsylvania,have invented certain Improvements in Car-Door Fastenings, of which thefollowing is a specification. My invention relates to that class offreightcar-door fastenings in which a seal is combined with the hasp sothat the door cannot be opened until this seal is destroyed.

The object of my invention is to socombine the seal with the lockingmechanism of a fastener that the seal will retain the said mechanism inthe locked position until it has been broken or otherwise destroyed,when on the breaking of the seal the locking mechanism will be releasedso that the hasp can be withdrawn from the keeper without furthermanipulation. This object I attain in the following manner, referencebeing had to the accompanying drawings, in which- Figure 1 is a frontview of my improved car-door fastening. Fig. 2 is a sectional plan viewof the same. Fig. 3 is atransverse sectional View on the line 3 3, Fig.2. Fig. 4 is a perspective view of the parts detached. Fig.

'5 is a perspective view of one of the toothed segments.

A is the frame of the car, and A is the door on which the hasp D issecured by means of the staple a; butiother means of fastening may beemployed without departing from my invention. On the end of the hasp Dis a box D open at front and back and closed at the sides. Secured toeach side of this box are spring-pawls d d, which are mounted, in thepresent instance, in channels cut in the box.

F is a keeper having a shell F adapted to fit the box D of the hasp D.Pivoted in the shell at e are segments E, two in the present instance,each segment having a series of ratchet-teeth a, with which the pawls clcl on the hasp D engage. The keeper F has an attaching-bolt f extendinginto the frame of the car. It will be noticed that the segments arepivoted off center, and the surface 6 of each segment is flat, so thatwhen the sealplate Gis slipped in the groove f in the shell F it willlock the segments in the position shown in Fig. 2, and prevent them fromdisengaging with the spring-pawls d (2 carried by the hasp D.

It will be noticed that when the hasp is placed in position over thekeeper the springpawls will yield so as to pass over the teeth on thesegments, but the teeth of the segments will prevent the removal of thehasp until they are released and allowed to swing on the pivots by theremoval of the sealplate G; and as the box D of the hasp extends beyondthe groove in the shell F for the reception of the seal-plate, saidplate cannot be removed from the groove except it be broken. I prefertomake this plate of some fragile metal or glass, and it is my presentintention to make it simply of cast-iron, and I prefer to indicate theroad by which the lock is used on the seal itself by perforating theseal with the initials of the road, as i11- dicated in Fig. 4E; and theseal is of sufiicient size to place other characters thereon-forinstance, the number and the division in which the car is sealed. Bythis arrangement it will be impossible to break the seal of a certaindivision and patch the seal again, as is now frequently done where alead seal is used, as it will be impossible to replace the seal in theshort time allowed.

It will be understoodthat in some cases a single segment may be usedinstead of the two segments, as shown, although I prefer to use the twosegments so that the jar of the car during its travel will not loosenthe fastening.

I claim as my invention- 1. The combination in a car-door fastening, ofthe keeper, locking mechanism carried thereby, a hasp having a boxinclosing the keeper with which said locking mechanism engages, a sealretaining said locking mechanism in a fixed position said seal beingconfined by the box, the parts being so arranged that when the seal isbroken the locking mechanism will be automatically released so that thehasp can be removed, substantially as described.

2. The combination in a door-fastening, of the keeper havinga shell, atoothed segment pivoted thereto, a seal adapted'to the shell and toretain the segment in a locked position, a hasp, a pawl on said haspengaging with the segment, the parts being so arranged that IOO on thebreaking of the seal the segment will ments and to confine them in thelocked pobe automaticallyreleased so that the hasp can sition, a hasphaving a box, spring-pawls in be removed, substantially as described.said boX engaging with the segments, said I 5 3.
